Answer:
He will require 5400 seconds
Step-by-step explanation:
Given:
The total distance he has to cover = 48 miles
The speed he is moving = 32 mph
To find :
Time in seconds = ?
Solution:
As given in the question that he is moving with a constant speed of 32 mph and he has to cover a distance of 48 miles at this speed so we will be using distance formula for finding the time taken by him
Formula is
Distance = speed * time
here we have to find time so
Time =
Putting in the values we get
Time =
Dividing it gives us
Time = 1.5 hours
As we need the answer in seconds and we know that
one hour has = 3600 seconds
so
Time = 1.5 * 3600 seconds
Time = 5400 seconds
Incomplete Question the Complete Question is here
Refer to the diagram below. Surveyors know that ∆PQR and ∆STR are similar. What is PQ, the distance across the lake?
3.20 km
3.60 km
2.80 km
3.24 km
Answer:
The Last option is correct 3.24 km
Therefore the distance across the lake is PQ = 3.24 km.
Step-by-step explanation:
Given:
ΔPQR and ΔSTR are Similar
ST = 1.80 km
TR = 1.25 km
QR = 2.25 km
To Find:
Distance across the lake, PQ = ?
Solution:
ΔPQR ~ ΔSTR ..........Given:
If two triangles are similar then their sides are in proportion.
Substituting the values we get
Therefore the distance across the lake is PQ = 3.24 km.
