Answer:
total distance = 320 miles
Explanation:
The question tells us the average speeds and time taken for two separate journeys made by Paige and asks us to calculate the total distance of the two journeys.
In order to calculate the distance travelled, we have to use the following formula for average speed:
.
Rearranging the above formula to make distance travelled the subject of the equation, we get:
distance travelled = average speed × time taken
Therefore, for the first journey:
• distance travelled = 60 m/h × 3.5 h
= 210 miles
And for the second journey:
• distance travelled = 55 m/h × 2
= 110 miles
Hence, the total distance travelled by Paige = 210 + 110
= 320 miles
