Question

A person travels by car from one city to an-

Answer 1

Answer:

Explanation:

First, let's refer to the distance formula:

$d=v*t$, where d is distance, v is velocity or speed and t is time.

Now, let's find the distance covered by each individual speed that the car had:

1. Speed 1.

In order to use the formula, we need to convert minutes into hours since the speed is given in km/h.

21.1 min/60= 0.35 h.

Now, apply the distance formula.

d=(0.35h)*(86.8km/h)= 30.38 km.

2. Speed 2.

Convert minutes to hours again and do the same calculations.

10.6min/60=0.18h

d=(0.18h)*(106km/h)= 19.08 km.

3. Speed 3.

36.5min/60= 0.61h

d=(0.61h)*(30.9km/h)= 18.85 km.

4. Obtain the total distance.

The total distance must be given by the addition of all individual distances traveled by the car on each speed:

Total distance= 30.38 km + 19.08 km + 18.85 km= 68.31 km.
