Answer:
Tomi's slowest possible walking speed is 80 meters per minute
Step-by-step explanation:
Tope swims at a speed of 50 meters per minute
Distance back and forth the long side of the pool is 50+50 meters = 100 meters
Time required to complete one round (back and forth) is 100 / 50 = 2 minutes
Perimeter of the pool is 50+50+30+30 = 160 meters
To walk around the perimeter and meet Tope at the starting point, Tomi has to walk 160 meters in 2 minutes
Tomi’s speed = 160 meters / 2 minutes or 160 / 2 = 80 meters per minute
Tomi's slowest possible speed should be 80 meters per minute
Let x be the larger number and y be the smaller number.
Using the given info, we get
x = 4y - 2
We also know that
x + y = 18
Substitute x = 4y -2 into x + y = 18
(4y -2) +y = 18
5y - 2 = 18
5y = 20
y = 4
Enter this value into x = 4y - 2
x = 4(4) - 2
x = 14
The larger number is 14 and the smaller one is 4.
Answer:
x = 64.307
Step-by-step explanation:
45.987+18.32= 64.307
