Question

Distance (meters)
time (seconds)
A
114

Answer 1

Time = 91.2 seconds

Explanation:

Since, Tyler swims at a constant speed 5 meters every 4 seconds.

Relation between distance and time is always proportional.

Therefore, d ∝ t

d = kt

Here, k = proportionality constant

For d = 5 m and t = 4 seconds

5 = 4k

k =
`(5)/(4)` = 1.25

So the relation is, d = 1.25t

Now we have to find the time taken to cover 114 m.

From the given relation,

114 = 1.25t

t =
`(114)/(1.25)`

t = 91.2 seconds
