In t hours the train has traveled s miles. Find the formula for v, the speed of the train (in mph) in terms of t and s. Find the
Digiron [165]

Answer:

Part 1 .

As per the given statement: In t hours the train has traveled s miles.

Distance of the train = s mile

Time = t hours

Formula for :

Speed of the train(v) = \frac{\text{Distance of the train}}{\text{Time}}

or

v = \frac{s}{t} mph           .....[1]

Substitute the value of t = 3 hours and s = 180 miles in [1], to solve for v;

v = \frac{180}{3} = 60 mph

Therefore, the speed of the train(v) is, 60 mph

Part 2.

Similarly,

The formula for speed of the train (v) is given by;

v =\frac{s}{t}

Substitute the value of t = 2.5 hours and s = 225 miles to solve for v;

v = \frac{225}{2.5} = 90 mph

Therefore, the speed of the train(v) is, 90 mph
