Question

Q44. City Y is half way between two other cities X and Z. All are alongside the river. X boat can go from X to Y and back in 2 h and 15 min and from Z to X in 3 h/min how long would it take to go from 2 to X?

• A. (a) $1^{\frac{1}{3}}h$
• B. (b) $1^{\frac{1}{2}}h$
• C. (c) $1^{\frac{3}{4}}h$
• D. (d) $1^{\frac{5}{6}}h$

Answer 1

The correct option is A

(a) $1^{\frac{1}{3}}h$

Time from X to Y and back = 2h 15 min

Time from x to z and back [double (i)] = 4h 30min.

Since time from Z to X is 3h 10 min

Time from X to Z is 1h 20min
