Q. The formula for the distance traveled over time

t

and at an average speed

v

is

d = v \times t

. Amit ran for

40

minutes at a speed of about

5

kilometers per hour. What calculation will give us the estimated distance Amit ran in kilometers?

Identify Formula: Identify the formula for distance traveled over time at an average speed. $\newline$ The formula for distance is $\text{Distance} = \text{Speed} \times \text{Time}$ . $\newline$ Here, we need to make sure that the units for $\text{speed}$ and $\text{time}$ are compatible before we perform the calculation.
Convert Time to Hours: Convert the time Amit ran from minutes to hours. $\newline$ Amit ran for $40$ minutes. Since there are $60$ minutes in an hour, we convert $40$ minutes to hours by dividing by $60$ . $\newline$ Time in hours = $40$ minutes / $60$ minutes per hour = $\frac{2}{3}$ hours.
Calculate Distance: Calculate the distance using the formula and the converted time. $\newline$ Distance = Speed * Time $\newline$ Distance = $5$ kilometers per hour * $\frac{2}{3}$ hours
Perform Multiplication: Perform the multiplication to find the distance. $\newline$ Distance = $5 \times \frac{2}{3}$ $\newline$ Distance = $\frac{10}{3}$ $\newline$ Distance = $3.333\ldots$ kilometers
