Find the distance speed=72km/h time=45mins

butalik [34]

The distance is 54 km if the speed and time are 72 km/h and 45 minutes respectively.

<h3>What is distance?</h3>

Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.

We have:

Speed = 72 km/h

time = 45 mins = 45/60 = 0.75 hours

We know,

Distance = Speed×time

Distance = 72(km/h)×0.75(h)

Distance = 54 km

Thus, the distance is 54 km if the speed and time are 72 km/h and 45 minutes respectively.

postnew [5]

Answer:

$62 = 4x + 2 \\ 12y = 144 \\ \\ 4x = 62 - 2 \\ 4x = 60 \\ x = \frac{60}{4} \\ x = 15 \\ \\ y = \frac{144}{12} \\ y = 12$
