A broken clock loses four minutes every hour . If the broken clock and a normal clock are both set at noon what time will the normal clock say when the broken clock reads 2:20pm

Time in normal clock = 2:30 PM

Step-by-step explanation:

Given:

Clock losses 4 min per hour

Total time = 2:20 Pm

Find:

Time in normal clock

Computation:

Total time = 2:20 = 2.333 hour

Total time losses = 2.333 x 4 min = 9.32 minutes (Approx)

Time in normal clock = 2:20 + 9.32 minutes (Approx)

Time in normal clock = 2:29.32 0r 2:30 PM

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
