Question

xample 8.2 The odometer of a car reads
2000 km at the start of a trip and
2400 km at the end of the trip. If the
trip took 8 h, calculate the average
speed of the car in km h' and m s.​

Answer 1

Answer:

km/h = 50km/h m/s = 13.8889m/s

Explanation:

1.Solving in km/h

distance travelled = 400km

time taken              = 8hrs

speed in km/h (d/t = s) = 400km/8h = 50km/h

2.Solving in m/s

distance travelled = 4000000m

time taken              = 28800s

speed in m/s          =4000000m/28800s = 13.8889m/s

Expert Answer :)

km/h = 50km/h m/s = 13.8889m/s

Explanation:

1.Solving in km/h

distance travelled = 400km

time taken              = 8hrs

speed in km/h (d/t = s) = 400km/8h = 50km/h

2.Solving in m/s

distance travelled = 4000000m

time taken              = 28800s

speed in m/s          =4000000m/28800s = 13.8889m/s
