Answer:
305 miles
Explanation:
You want to know how far Dylan travelled if he drove 50 mph for 3.5 hours and 65 mph for 2 hours.
Distance
Distance is the product of speed and time. The total distance Dylan travelled will be the sum of lengths of the legs of his trip.
distance = speed · time
total distance = speed1 · time1 + speed2 · time2
= (50 mi/h)(3.5 h) +(65 mi/h)(2 h) = 305 mi
Dylan travelled a total of 305 miles.
