Question

The odometer of a car reads 2000 km at the start of a trip and 2288 km at the end of the trip. If

the trip took 8h, calculate the average speed of the car in a) kmp/h b) m/s.​

Answer 1

Explanation:

2288-2000=288

speed=d/t

288km/8h

=36km/h

36km/h=36×1000/60×60

10m/sec

Answer 2

Answer:

at start of the trip = 2000 km

at the end of the trip = 2288 km

total distance covered = 2288 - 2000

= 288 km

time taken = 8 hours

therefore average speed in kmph = 288/8 = 36kmh

average speed in m/s = 8 hours = 480 mins

480 mins = 28800 secs

km = 288 km = 288000 m

average speed in m/s = 288000/28800

= 10 m/s

average speed

a) 36kmph

b) 10 m/s
