A Tata Indica car started from Mumbai towards Kolkata at 6 am and travelled at an average speed of 60 km/hr. It was found that an important material to be sent to Kolkata was omitted to be included in the packets sent in Tata Indica car. The omitted material was carried on an Innova car that started at 8.15 am and travelled with an average speed of 90 km/hr. At what time Innova car will cross Tata Indica car ?
a)1.15 pm b)3.15 PM c) 12.45 pm d) 4.15 pm

- Indica had started 2 hours 15 mins in advance to that of Innova Car
Before, Innova started, Tata Indica covers a distance of 135 km in 2 hours and 15 minutes. (you can check this by using the formula Speed x Time where speed of Indica = 60km)
Innova travels at 90 km/hr.
Relative speed of Innova with respect to Indica = Speed of Innova - Speed of Indica = 90 - 60 = 30 km/hr
Time that would be taken by Innova to catch up with Indica = Distance Difference at Start of Innova/ Relative Speed of Innova with respect to Indica = 135/30 = 4 1/2 hours for Innova to cross Tata Indica
Innova started at 8.15 am . It will cross Tata Indica at 12.45 pm. - 12 years agoHelpfull: Yes(3) No(0)
- c) 12 . 45 p.m
Indica had started 2 hours 15 mins in advance to that of Innova Car
Before, Innova started, Tata Indica covers a distance of 135 km in 2 hours and 15 minutes. (you can check this by using the formula Speed x Time where speed of Indica = 60km)
Innova travels at 90 km/hr.
Relative speed of Innova with respect to Indica = Speed of Innova - Speed of Indica = 90 - 60 = 30 km/hr
Time that would be taken by Innova to catch up with Indica = Distance Difference at Start of Innova/ Relative Speed of Innova with respect to Indica = 135/30 = 4 1/2 hours for Innova to cross Tata Indica
Innova started at 8.15 am . It will cross Tata Indica at 12.45 pm. - 10 years agoHelpfull: Yes(1) No(0)
