A car travels at a speed of 70km/h. What distance will it cover in 30 minutes

Answer 1

time = 30 minutes = 30/60 hour = 0.5 hour
speed = 70 km/hour

Use the equation
Distance = time * speed
to find distance, AFTER making sure the units used are consistent.

Answer 2

time = 30 minutes = 30/60 hour = 0.5 hour
speed = 70 km/h
Distance = time * speed
Distance = 0.5 * 70 km/h
DISTANCE = 35
