23. Jane arrived home in the time shown on the clock face. Step 1: Tambua mshale mfupi (mshale wa saa). Mshale mfupi unaelekeza kati ya 2 na 3. Hii inamaanisha saa ni 2. Step 2: Tambua mshale mrefu (mshale wa dakika). Mshale mrefu unaelekeza kwenye nambari 7. Kila nambari kwenye saa inawakilisha dakika 5. Kwa hivyo, 7 inawakilisha 7 × 5 = 35 dakika. Step 3: Unganisha saa na dakika. Muda ulioonyeshwa ni 2:35. Step 4: Badilisha muda kuwa maneno na ulinganishe na chaguzi zilizopewa. Muda wa 2:35 unaweza pia kusemwa kama "dakika ishirini na tano kabla ya saa 3 kamili" (60 - 35 = 25 dakika zimesalia hadi saa 3). A. half past 3 (3:30) - Sio sahihi. B. twenty five minutes to 3 O'clock (2:35) - Sahihi. C. quarter past seven (7:15) - Sio sahihi. D. quarter to 2 o'clock (1:45) - Sio sahihi. Jibu sahihi ni B.
