Answer:

50 minutes

Step-by-step explanation:

Given:

\bullet \ \ \text{Monday:} \ \dfrac{2}{3} \times \text{Hour}\\\\\bullet \ \text{Wednesday:} \ \dfrac{1}{2} \times \text{Hour}

Since Emily only practiced on Monday and Wednesday, the sum of time on both days is the time Emily practiced on the piano for a week.

\implies \text{Monday + Wednesday = Total time practiced on piano for a week}

<u>Substitute the times in the equation</u>

\implies (\dfrac{2}{3}  \times \text{Hour}) + (\dfrac{1}{2}  \times \text{Hour}) = \text{Total time practiced on piano for a week}

<u>Simplify the equation</u>

\implies (\dfrac{2}{3}  \times 60 \ \text{minutes}) + (\dfrac{1}{2}  \times 60 \ \text{minutes}) = \text{Total time practiced on piano for a week}

\implies (20 \ \text{minutes}) + (30 \ \text{minutes}) = \text{Total time practiced on piano for a week}

\implies \boxed{50 \ \text{minutes} = \text{Total time practiced on piano for a week}}

How do I work this out
Iteru [2.4K]
If the track is 10km long, and X travels at 40 km/h, it will take 1 hour to do 4 laps. this means that car X will do one lap in 15 minutes. Y travels at 30 km/h, which means it will do 3 laps in 1 hour, meaning that car X will do 1 lap in 20 minutes.

X- 15, 30, 45, 60
Y-20, 40, 60


Therefore, after an hour, they will pass again.
