Question

the odometer of a car reads 57321. 0 km when the clock shows the time 8:30 a.m.what is the distance moved by car if at 8:50 a.m. the odometer reading has changed at 57336.0 km? calculate the speed of car in kilometre per minute during this time Express the speed in kilometre per hour also

Answer 1

Reading at 8:30=57321 KM's

Reading at 8:50=57336 KM's

So distance travelled in 20 minutes= 57321-57336=15 KM's

Speed=15kms/20minutes

=3/4 KM's/ minute

=0.75kms/minute

=15kms/1/3hr

=15/1x3 KM's/hr

=45 KM's per hour
