Question

The odometer of a car reads 57321.0 km when the clock shows the time
08:30 AM. What is the distance moved by the car, if at 08:50 AM, the
odometer 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

Answer:

The odometer of car reads distance at the time of 8:30 AM= 57321 Km

The odometer of car reads distance at the time of 8:50 AM= 57336 Km

The distance covered by car within 20 minutes (8:50 - 8:30) = 15 Km

Distance covered by car = 15 Km

Time taken by car            = 20 minutes

Speed of a car                 = Distance / Time

                                         = 15 /20 = 3/4 = 3 km/min

Converting minutes into hours

1 min = 1/60 hours

3/4 min = 3/4*60

Speed of a car is 120 km/h
