A plane travels at a speed of 213 miles per hour - Edexcel - GCSE Maths - Question 6 - 2018 - Paper 1

To find the time taken to travel 1 mile at a speed of 213 miles per hour, we can use the formula:

$\text{Time} = \frac{\text{Distance}}{\text{Speed}}$

Substituting the values for Distance and Speed:

$\text{Time} = \frac{1 \text{ mile}}{213 \text{ miles per hour}}$

To convert the speed from miles per hour to miles per second, we can divide by 3600 (the number of seconds in one hour):

$213 \frac{\text{miles}}{\text{hour}} = \frac{213}{3600} \frac{\text{miles}}{\text{seconds}}$

Calculating the time:

• First, calculate the speed in miles per second: $\frac{213}{3600} \approx 0.05917 \text{ miles per second}$
• Now, finding the time taken to cover 1 mile: $\text{Time} = \frac{1}{0.05917} \approx 16.89 \text{ seconds}$

Thus, the time taken to travel 1 mile is approximately 17 seconds.
