Question

the odometer of a car reads 5732 1.0 km when the clock shows the time 8:30 a.m. is the distance moved by the car if at 8:50 a.m. the ordinator reading has changed to 57336.0 km ? calculate the speed of the car in km / min during this time express the speed in km / h also.

Answer 1

time=8:30
distance=57321

time=8:50
distance=57336

total time taken=20 minutes
total distance covered=57336-57321
=15 km
speed=20÷15=1.33km per minute
per hour=.02 km per hour

Answer 2

Hey dear,

● Answer -
v = 45 km/hr

● Explaination -
# Given-
s1 = 57321 km
s2 = 57336 km
t1 = 8.30 am
t2 = 8.50 am

# Solution-
Speed of the car is given by -
Speed = distance / time
v = (d2-d1)/(t2-t1)
v = (57336-57321)/(8.50-8.30)
v = 15×3
v = 45 km/hr
v = 12.5 m/s

Speed of the car is 45 km/h

Hope that is helpful...
