Question

Find the distance, when speed=80 km/h and time=3 hours

Answer 1

Step-by-step explanation:

given speed of the car = 80km/h

and to calculate the distance travelled by car in 3 hr and 30 minutes

so by this formula, distance = speed * taken time

thus distance = 80 * 7/2 = 280 km

here 3 hr and 30 min = 7/2 hr.

or

Given speed = 80 kmph, Time = 3 hours 30 minutes = 3 1/2 hours = 7/2 hours

Distance = Speed x Time = 80 x 7/2 = 280 kms.

Therefore, the distance travelled by the car moving at a speed of 80 kmph for 3 hours 30 minutes is 240 kms.

Answer 2

Answer:

240km/h is the answer.

Step-by-step explanation:

$speed \: = \frac{distance}{time} \\ d = 80 \times 3 \\ d \: = 240km/h \:$
