A man rides at a rate of 18 kmhr but stops 6 min at end of every 7 km .how long will he take to ride 90 km
Read Solution (Total 2)
-
- Every 7 km, he takes rest
90/7=12 times taken rest
so total rest time = 12*6= 72 min = 1 hr 12 min
speed=18 km/hr
distance= 90 km
time = (distance/speed) = 90/18 = 5 hrs
Total time = 5 hrs + (1 hr 12 min) = 6 hrs 12 min - 7 years agoHelpfull: Yes(12) No(0)
- TOTAL TIME TAKE FOR STOPS = 12 * 6 = 77 MINUTES
SPEED= 18 KMH
DISTANCE = 90 KM
TIME TAKEN TO COVER 90 KM = (90/18 ) + 77 MINUTES
= 6 HOURS 17 MINUTES - 5 years agoHelpfull: Yes(0) No(4)
