Answer:
12 km
Step-by-step explanation:
Using the formula <em>rate × time = distance:</em>
Jogging = 12 km/h × x = 12x
Walking = 8 km/h × (x + 0.5) = 8x + 4
Setting the two terms equal:
12x = 8x + 4
Subtracting 8x from both sides:
4x = 4
Dividing both sides by 4:
x = 1
Therefore, it takes 1 hour of jogging or 1.5 hours of walking to travel from the school to the pool. Thus, they are 12 km [12 km/h × 1 h <em>or</em> 8 km/h × 1.5 h] apart.
Answer:
l=200 yard
w=70 yard
Step-by-step explanation:
let width =w
length l=2w+60
then perimeter P=2(l+w)=2(2w+60+w)=540
3w+60=270
3 w=270-60=210
w=70
l=2*70+60=200
