Answer:
3:50pm
Time Keisha went to the park- 1:30pm
Time spent for hiking- 1hour 35 minutes
Time spent at the picnic area- 45 minutes
1: 30pm
<u>+1. 35mi</u>n
<u> 2: 65pm</u>
But 60 minutes is 1 hour so the 65 will be changed to 1 hour 5 minutes making it
3: 05pm
3: 05pm
<u>+0: 45min</u>
<u> 3: 50pm</u>
Hence the time Keisha left the park was 3:50pm
Answer:
<h3>t = 15d</h3>
Step-by-step explanation:
You must first know that 1 week = 7days
If Sophie practices the piano 105 minutes in 1 week, this can be expressed as;
105 minutes = 7days
to calculate the total time t that she practices for any number of days, d, we will say;
t minutes = d days.
Solving both expression;
105 minutes = 7days
t minutes = d days.
Cross multiply;
7 * t = 105 * d
7t = 105d
Divide both sides by 7;
7t/7 = 105d/7
t = 15d
Hence a proportional equation for t in terms of d that matches the context is expressed as t = 15d
