Question

"Doris drives to a Maths Convention, which is 72km away. She drives at an average speed of 45km/h

She sets off at 2.54pm.
When does she arrive?"

Answer 1

Doris will arrive at the Maths Convention at 4.14pm.

Step-by-step explanation:

To calculate the time it takes for Doris to arrive at the Maths Convention, we can use the formula:

Time = Distance / Average Speed

Given that the distance is 72km and the average speed is 45km/h, we can substitute these values into the formula:

Time = 72km / 45km/h

Simplifying the expression gives:

Time = 1.6 hours

Since Doris sets off at 2.54pm, we need to add 1.6 hours to find the arrival time:

2.54pm + 1.6 hours = 4.14pm

Therefore, Doris will arrive at the Maths Convention at 4.14pm.
