Answer:

Unitary method:

a car travels 60 km in 30 minutes

1 km ---------> 30÷60  = 1/2 minutes

100 KM ------>   1÷2×100 = 50 minutes

Answer:

About 40 Minutes, Or something close to that

Step-by-step explanation:

The car covers 60 km in 90 minutes or its speed = 60 km*60/90 min = 40 km/hr . So to cover 100 km at the same speed it will take 100/40 = 40 Min

If p and q vary inversely and pp is 23 when q is 6, determine q when p is equal to 69.
Lina20 [59]

Answer:

Answer is q = 2

Step-by-step explanation:

First make the equation with a constant so p=k/q

then substitute q to 6 and p to 23.

Then you have 23=k/6 and to find k multiply both sides to get k=138

next substitute p as 69=138/q then multiply q on both sides to get 69xq=138 and then divide 69 to 138 go get q which is 2
