The speed of an object is its distance traveled per unit time
The average speed required for the remainder of the trip <u>55.5</u>
<u />
The reason the average speed value is correct is given as follows:
The known parameters;
The length of the first part of the trip, L = 218 mile
Duration of the time the sales person travels, t₁ = 2 hours and 15 minute
Average speed of travel, v₁ = 64 mph
The time at which the salesperson arrive at the destination, t₂ = 1 hour and 20 minutes
Required:
To find the average speed required for the remainder of the trip
Solution:
Distance traveled = Speed × Time
The distance traveled on the first part of the trip, <em>d₁ = v₁ × t₁</em>
(t₁ = 2 hours and 15 minute = 2.25 hours)
∴ d = 64 mph × 2.25 hours = 144 miles
The distance of the remainder part of the trip, d₂ = L - d₁
d₂ = 218 mile - 144 mile = 74 mile
The average speed required for the remainder of the trip, v₂, is given as follows;
t₂ = 1 hour and 20 minutes =
Therefore;
With the units left out, we have;
<u>The average speed required for the remainder of the trip, v₂ = 55.5</u>
