Baltimore is approximately 410 miles away from Boston. Determine Dennis's average speed from Hartford to Baltimore if that noition of his trip takes 5 hours.​

Answer 1

61.8 miles/hr

Explanation:

Given that

Dennis starts from Boston and travels to Hartford for 101 miles.

And then he travels towards Baltimore which is 410 miles away from Boston.

Time taken from Hartford to Baltimore = 5 hours

Kindly refer to the image attached for the trip of Dennis and the distance traveled by him.

Point A represents Boston.

Point B represents Hartford.

Point C represents Baltimore.

Distance AB = 101 miles

Distance AC = 410 miles

Actually, we are given that Distance BC is traveled in 5 hours.

Distance BC = AC - AB = 410 - 101 = 309 miles

Average Speed is given as:

`\text{Average Speed = }\frac{\text{Total Distance traveled}}{\text{Total Time Taken}}`

So,

`\text{Average Speed = }(309)/(5)\\\Rightarrow \text{Average Speed = }\bold{61.8\ miles/hr}`
