If a heavy-load trailer travelled 7 km in 1 hour and 10 minutes, what was its speed in km per hour?
Read Solution (Total 7)
-
- 6km/hr ans.
sol:-
total distance=7km
total time=1 hour and 10 minutes=70minutes=70/60 hrs=7/6hrs
from distance formula,
Average speed=total distance/total time=7*6/7km/hr=6km/hr ans. - 12 years agoHelpfull: Yes(16) No(0)
- It is 6km/hr
distance=7km time=1 hr 10 min i.e 7/6 hrs
we knw that speed=dist/time
=7/(7/6)
=6km/hr - 12 years agoHelpfull: Yes(3) No(5)
- First we calculate the speed per minute
1 hour = 60 minutes
1 hour and 10 minutes = 60 + 10 = 70 minutes
7 km travelled in 70 minutes
travelled in 1 minute = 7 ÷ 70 = 0.1
speed in km per hour = 0.1 x 60 = 6
The answer is 6 km per hour - 12 years agoHelpfull: Yes(2) No(0)
- approx 11.42minutes per km
7km = 80minutes (since, 1hour and 10mintes = 80mintutes)
1km = 80/7
1km = 11.428571minutes - 12 years agoHelpfull: Yes(1) No(7)
- in 1 hr 10 min it moves = 7km
in 70 min = 7000 met
1 min = 100 met
60 min = 6000 met
1 hr = 6 km
speed is 6 kmph. - 12 years agoHelpfull: Yes(1) No(1)
- d=7km
t=70/60hr
s=d/t=7*6/7=6km/hr - 12 years agoHelpfull: Yes(1) No(0)
- Approx 11.42 km per hour.
7km = 80minutes
1km = 80/7
