Question

You are driving to your grandparents which is 95km away. If I drive at an average speed of 85km/h, how long will it take to get there?

Answer 1

To drive 95 km at an average speed of 85 km/h, it will take approximately 4 hours and 1 minute.

Step-by-step explanation:

To calculate the time it will take to drive 95 km at an average speed of 85 km/h, you can use the formula

Time = Distance / Speed

Substituting the values, we get:

Time = 95 km / 85 km/h

To simplify the calculation, you can convert the speed to meters per second

85 km/h = 85,000 m / 3,600 s = 23.61 m/s

Now, we can calculate the time

Time = 95 km / 23.61 m/s = 4.02 hours

Therefore, it will take approximately 4 hours and 1 minute to get to your grandparents' house.

Answer 2

Time = 1.118 hours

Step-by-step explanation:

Given the following data;

Distance = 95 km

Speed = 85 km/h

To find how long will it take to get there;

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the formula;

`Speed = (distance)/(time)`

Making time the subject of formula, we have;

`Time = (distance)/(speed)`

Substituting into the equation, we have;

`Time = (95)/(85)`

Time = 1.118 hours
