Question

Ben and Carl participate in a 200 m race.
Ben is the first to reach the finish point, while Carl is behind by 20 m or 5 seconds.

Find how much time will Carl take to complete the 200 m race.

• A. 55 seconds
• B. 60 seconds
• C. 50 seconds
• D. 45 seconds

Answer 1

The correct option is C 50 seconds

Total distance = 200 m

When Ben reached the finish point, Carl was behind by 20 m.

Time taken to cover 20 m = 5 seconds
$\text{∴ Time taken to cover 1 m}=\frac{5}{20}$

$=\frac{1}{4}\text{seconds}$

$\text{Time taken to cover 200 m}=\frac{1}{4}\times 200$

= 50 seconds

Thus, Carl will be able to cover the total distance in 50 seconds.
